To a/ZZ whom t may concern/:

B e it known that I7 OLAF' ',SAuesTAn, a citimotors of the type known as fluid-pressure motors. i l

My invention comprises a motor of this type suspended from a point concentric with the pivotal axis of the damper and a direct connection between the movable wall of the motor and a portion fast with the damper.

The objects of my invention are to provide convenient means forsupporting kthe motor and to provide means whereby the motor' may be adjusted in varying positions while employing the same connections, and, further, to do away withthe usual intermediate connections employed between the movablel Wall and the damper. j

My invention also consists in certain details of construction and 'combination of parts, as will hereinafter be more fully set forth. -v l .I will now proceed to describe a device embodying my invention and will then point out thel novel features in claims.

In the drawings, Figure 1 is a view in central vertical section of a damper-operating motor embodying my invention, showing the same suspended. from a pipe-collar, the pi ecollar and certain parts connected therewith being shown 'inl side elevation. Fig. 2 is a view in central-transverse vertical section through the same. l

1 designates a pipe-collar forming a coupling for pipe-sections 2 2. The pipe-collar forms a support for a darn er 3, mounted upon a pivoted spindle-4. T e spindle 4, ex-

tends `to the exterior of the collar through a adjusted in position. The motor includes a' diaphragm-chamber 10,a diaphragm 11, and a follower 12. VThe follower 1'2 has an arm 13,-r'igidly secured 'thereto or fortified'y as Ya part thereof, said rodbeingpivoted at itis outer` end to awr'ist-pin 14,'cfarri'ed by 'a crankarm 15, securedfup'on' the spindle' 4' of the damper. A ipe 16 admits fluid under pressure to the c amber 10 to forcethemovable wallcomprised in the diaphragm 11 and follower 12 outward, and so to rotate the damper upon its axis to close same. A spring 17 returns the parts to their normal positions vupon exhaust of fluid under pressure from the chamber 10. The crank-arm15 is secured in position upon the spindle 4, preferably by means of a set-screw 18, whereby the said arm may be initially *adjusted to its proper relative position with respect to the damper and afterward secured in the position to which it is adjusted.

By the foregoing it will be seen that I have provided a means for supporting the damperoperatingmotor directly from the dampercollar and that by such means, comprising a suspension device axially concentric with the axis of the damper, it is possible to initially adjust the motor to any position around the said axis-that is to say, vertical, oblique,.

horizontal, inverted, or the likewithout providing any special connections or any intermediate parts. In 'order to change the positions, it is only necessary to loosen the set-screwsQ and 1S and again tighten them after the parts are properly adjusted. It will also be seen that I have entirely done'away with the usualintermediate connections between the movable wall of the damper and the damper itself. j The flexibility of the diaessary for the end ofthe rod 13 to follow the arc describe-d by the crank-arm 15,.so that there will be no straining of the parts or lost motion required. Y It will also be seen that the collar, damper, and motor become a selfcontained device whichmay be fitted in position upon any pipe without the necessity of connections with other parts, as has been usual heretofore.

What I claim is- 1. In a device of the character described, the combination with av pivoted damper and means for supporting same, of a motor for op- ,phragm 11 permits the slight movement nec- Ioo erating said damper suspended from said supporting means concentrically With the axis of said damper.

2. In a device of the character described, the combination/with a pivoted damper and a crank-arm secured thereto, of means for supporting said damper, and a motor for operating said damper suspend ed from said supporting means concentrically With the aXis of said damper, said motor directly connected With the said crank-arm.

3. In a device of the character described, the combination with a pipe-collar and a damer pivoted thereto, said pipe-collar having a ub concentric With the pivot of said damper, of a fluid-pressure motor provided With a movable Wall, suspended from said hub, a crank-arm connected With the damper, and a OLAF SAUGSTAD.
